Metso to supply emission-reducing automation technology to power producers in various parts of Europe

Published Feb 10, 2011 18.24.40 +2 GMT

During recent months, Metso has received orders for automation technology solutions that enable power producers in various parts of Europe improve their energy efficiency and lower their environmental load significantly.

Metso’s R&D has focused on technologies with which power producers can minimize the consumption of energy and raw materials as well as emissions. “For example, technologies related to combustion process optimization play a key role when modern power plants look for ways to improve energy efficiency and decrease emissions. Through the use of new technologies, it’s possible to boost eco-efficiency at traditional coal-fired plants, too,” says Kari Huovila, Vice President, Energy & Process Systems.

Metso will supply advanced combustion management systems for the reduction of emissions at the 225 MW Jaworzno III power plant in southern Poland. The project will be carried out in close cooperation with Fortum Power and Heat Oy, Power Solutions, a company responsible for the modernization of six coal-fired boilers at the plant. The project is the largest of its kind ever in Poland that aims at climate change mitigation through the reduction of nitrogen oxides (NOx).

Metso’s delivery scope includes an Advanced Process Control (APC) solution running on the metsoDNA CR automation and information platform. Based on a fuzzy logic controller, it will coordinate, supervise and optimize the combustion process efficiently in real time. The solution enables the plant to reduce and stabilize its NOx emissions with minimized urea consumption, as well as to reduce unburned carbon in flue gas (UBC). Other system benefits include improved efficiency, faster recovery of load disturbances, and less need for manual intervention.

Today, old coal-fired boilers are often replaced by biomass-fired ones. Metso will supply an energy automation system to the new 50 MW biomass CHP plant being built by RWE npower renewables in Markinch, Fife, Scotland. The design, supply, installation, construction and commissioning for the plant is provided by Aker Solutions. The new 50 MW plant will reduce the site’s carbon footprint by 72%, helping to reduce the annual fossil fuel carbon emissions at the company by 250,000 tons per year.

The delivery by Metso consists of a metsoDNA single architecture control system for the plant consisting of a 155 MWth circulating fluidized bed (CFB) boiler, a steam turbine plant and a fuel handling plant. The new power boiler will also be supplied by Metso.

In addition to the above orders, Metso has also received orders from England, Portugal and Ireland. For example, Metso will supply automation to a 40 MW cogeneration plant being built in the Artenius Sines petrochemical industrial park in Portugal. The scope includes a metsoDNA distributed control system featuring an integrated trend, event archive and reporting system. The turnkey delivery also covers system engineering, factory acceptance tests, commissioning as well as training for the operation and maintenance teams.

Metso is a global supplier of sustainable technology and services for mining, construction, power generation, automation, recycling and the pulp and paper industries. We have about 28,500 employees in more than 50 countries.
